Improving Cognition Via Exercise in Schizophrenia

The goal of the proposed study is to examine the impact of remote exercise training on cognitive functioning in people with schizophrenia. People with schizophrenia display a broad range of cognitive impairments that have been identified as major determinants of poor functional outcome and disability, thus representing an important public health concern and a target for interventions. At present, available treatments offer only minimal to limited benefits to ameliorate these deficits. Extensive animal and human research literatures converge in supporting the positive influence of aerobic exercise training on cognitive functioning. Preliminary data indicate that aerobic exercise training is effective in improving cognitive functioning in people with schizophrenia. However, previous studies employed small samples, focused on a single or limited range of cognitive domains, and/or collected insufficient information on daily functioning or putative biomarkers underlying cognitive change. Supported by supplement funding from NIMH, the goal of the proposed study is also to explore the impact of remote exercise training on suicide risk in individuals with schizophrenia. People with schizophrenia are at increased risk for suicide, with approximately 40-50% of individuals attempting to take their own lives during their lifetime, and an estimated 5-10% actually being successful in completing suicide. This highly elevated risk represents a serious public health concern and an important target for interventions. However, available treatments offer only minimal to limited benefits to ameliorate this risk. Extensive animal and human research literatures converge in supporting the positive influence of AE training on a number of predictors of suicide risk including depressed mood, sleep difficulties, and poor cognition. Yet, at present there are no studies directly examining the impact of AE on suicide risk in this population.
